Like the queued spinlock enabling patch, if this will be on all the time for SPARC64 then:
> diff --git a/arch/sparc/include/asm/spinlock_64.h b/arch/sparc/include/asm/spinlock_64.h > index 562dbd8..e2044e3 100644 > --- a/arch/sparc/include/asm/spinlock_64.h > +++ b/arch/sparc/include/asm/spinlock_64.h > @@ -11,6 +11,9 @@ > #include <asm/processor.h> > #include <asm/barrier.h> > > +#ifdef CONFIG_QUEUED_SPINLOCKS > +#include <asm/qspinlock.h> > +#else
This ifdef doesn't make any sense, by definition it will always be on.
